This release contains improvements to telephony models for English and Spanish, and a number of bugfixes.
The following languages now support advanced punctuation: English (en), German (de), Spanish (es), French (fr), Dutch (nl) and Danish (da).
It is recommended that customers on previous releases upgrade to this version.
The legacy V1 API that the Batch Virtual Appliance currently supports will be discontinued in a future release as we align the product with the same V2 API used by the Speechmatics SaaS: https://asr.api.speechmatics.com/v2/docs. We recommend that customers familiarise themselves with the configuration object used to specify job configurations, and only use form parameters for callback notifications. Future notices will be provided to announce the end of life of the V1 API, and provide detailed instructions on migrations to the V2 API.
The following issues are addressed since the previous release:
| Issue ID | Summary | Resolution Description |

| REQ-7268 | The internal 'reset' method can cause a server panic | This messages will now no longer be seen in the logs when services are restarted. |
| REQ-7461 | Memory leak affecting licensing container | A small memory leak affecting the licensing service has now been addressed. |
| REQ-9122 | Appliance could run into problems with services not being able to restart if it ran out of disk space. | The appliance will now reject jobs if there is < 250MB of free space on the disk. |

| REQ-10095 | StopIteration Exception in post processing can cause a job to fail | The exception is now handled properly. |
| REQ-11644 | Offline activation cannot generate deactivation code | Previously if you submitted the PUT/POST request for offlineactivation, any attempt to deactivate with a DELETE request failed; this has now been fixed. |
| REQ-11728 | Files less than 1 second skip decoding. | Files that are < 0.3s long are considered to be zero length; but files between 0.3 and 1.0s (and above) will now be transcribed (assuming speech is detected in them). |

| REQ-11135 | 3.2.0 introduced unwanted hesitations in transcripts for English (en). | Due to changes in the way that training data is now ingested to improve the accuracy of spontaneous speech for English (en) there is a greater likelihood that hesitations will be included in the output transcrtips. We plan to support a hesitation filtering capability in a future release for customers that do not want to see hesitations on transcripts. |
